Ok fellas I know the H190 alloy carrier is avail from early fairladys and some other van and trucks but after seen so many modern h190 going to the crushers at wreckers without salvage I think its time for a solution.

Most people prefer the R31 solution as they have an LSD solution readily available but its heavy and not 2 piece like the H190.
Now I would like to find a way to reproduce the H190 gear carrier in alloy and with an added sump like on alfa romeo differentials of yesteryear. Im thinking of getting a gear carrier in cast iron and adding all the alfa bits like sump and fins with extra re-inforcing using bog and aircraft steel putty for a final mold.

Any suggestions or issues I could run into as I have a casting place near by that does several kinds of car parts and are struggling for extra work.

this is the Alfa Romeo Masterpice next to a H165, also note this rear end was using behind 400hp Euro race Montreals and more.

Very interesting D! what i want to know is can this Alfa set up be adapted and shortened to suit a 1000? it doesn't look that much wider than the H165, and is this particular one LSD?

i'm very interested in this idea!

bit confused what you actually want to do, but there already is alloy gear carriers for these...

Yes as stated in first post avail but rare
so if Im going to make some then I want to go the whole hog.

The alfa diffs are rare as hens teeth in lsd and I only have 2 lsd centres

however I would like something easy to source before all the live axle rear wheel drive vanettes and utes are gone.

it is a great idea D! i will definatley buy one when you make enough to sell!
